ilna: I notice that error now on my Fedora 11.  I'm too lazy to check,
but it looks as if the kernel header changed and hijacked a symbol that
I had been using.

quick fix: issue this shell command in the mtrr directory
  sed -i -e 's/\<mtrr_type\>/&_dhr/g' mtrr-uncover.c

Then "make" again.


I am a bit surprised that you have MTRR problems when you are using a new kernel.  I would have thought that the kernel's code to "clean up" MTRRs would be working.  This code was added to the official kernel last year.

I would like to know more.

If you do report it as a new bug (and I don't know if you should report
a new bug or add to this report), please do add a comment here telling
us where to find the new report.
